What is the contolled and experimental group in an experiment?

Answer 1

Experimental control is a group of experimental subjects that is not exposed to a chemical or treatment being investigated so that it can be compared with experimental groups that are exposed to the chemical or treatment

It is also the standard of comparison.

-Also, look for the following things:

Experimenter Bias, History, Maturation, Instrumentation, Selection, Order, and Statistical regression. All of these should be questioned.

Answer 2

While conducting an experiment, it is important to have a experimental control.

Suppose you are conducting an experiment to determine what factors affect the rate of evaporation of water. If you want to determine if presence of wind affects evaporation, you can take two containers of water and place one in a windy place and the other in a place with no wind. However all other factors should be identical like surface area of containers, surrounding temperature, liquid quantity and temperature etc.

Hence, the need for a controlled experiment is to eliminate bias and to ensure that the data is valid.

Answer 3

The controll is the group that has a similar experience but not subject to the substance in question. The experimental group is the group that is exposed to the substance in question.

For instance test to see if a certain drug reduces pain the controll group would receive fake pills and the experimental group would receive the drug. This is because sometimes just participating causes people to change their behaviour or feelings.

Answer 4

The experimental group is the group that gets a drug, pill or device that is supposed to have the effects on the experiment, the new pill that came out, see if it works. The control group is the group that gets a pill or device that does not have any effect on the experiment. This pill or device is called a placebo.

Answer 5

Control group is normal state and experiment group is factor changed. ^_^

Answer 6

control treatment is when you have something else that might cause your experiment

Answer 7

control group-the things that stay the same

experimental-the thing being tested on

Answer 8

The "independent" or "manipulated" variable is changed between the groups.

Answer 9

The experimental group is subjected to whatever is being tested. The control group is treated exactly the same way but without the test variable.
